MRI with contrast
An MRI with contrast uses an injection of a contrast agent (dye) to help highlight your blood vessels, organs, and soft tissues in greater detail.
What is an MRI with contrast?
Magnetic resonance imaging (MRI) is a type of scan that uses a magnetic field and computer-generated radio waves to produce detailed images from inside the body.
An MRI with contrast combines a standard MRI scan with an injection of a contrast agent (dye). This dye helps to highlight your blood vessels, organs and soft tissues, which makes them show up more clearly and in greater detail on the scan.
Your consultant may recommend an MRI scan with contrast if you have a suspected abnormality in an organ, such as the heart or brain. This type of scan is also particularly useful for assessing tumours.
An MRI scan is a safe and painless procedure, but there may be some instances where it isn’t suitable for you. This may be the case if:
- You are pregnant
- You have metal in your body
- You’ve had a previous allergic reaction to a contrast agent
- You have kidney problems.
A contrast agent is a special type of dye that is used to help highlight your blood vessels, organs and soft tissues on an MRI scan.
Most contrast agents contain a type of metal called gadolinium, which interacts with the MRI scanner’s magnetic field. These are known as gadolinium-based contrast agents (GBCAs). There are different types of GBCAs, which are used for different areas of the body.
GBCAs are usually administered intravenously (via an injection). They are safe to take and are usually passed out of the body through your urine within 24 hours.
An MRI with contrast is carried out by a radiographer – a health professional trained to carry out imaging procedures.
An MRI scanner is shaped like a tunnel which is open at both ends. You’ll lie on a motorised bed that moves into the scanner, either head or feet first.
Before you enter the scanner, you will be injected with the contrast agent through an IV line placed in your arm.
An MRI with contrast usually takes between 30-90 minutes to complete. You must keep still during the scan as the MRI scanner is very sensitive to movement.
You can go home directly after your imaging procedure. Your consultant will receive your results within 48 hours and follow up with you regarding next steps.
About our scanners
Cromwell Hospital uses scanners which are designed to create a calming atmosphere, with ambient audio-visual technology that allows you to enjoy music and a relaxing light show throughout your scan. Our scanners are also larger than traditional machines.
Basinghall Clinic uses one of the newer generation of MRI scanners. The tunnel of the scanner is bigger than most other scanners (70cm diameter/120cm length) and scans can often be done going into the tunnel feet first. Patients who have had problems with MRI claustrophobia in the past often find they are able to be scanned at our clinic.
